Abstract: ABSTRACT OF THE DISCLOSURE         In a centrifuge rotor provided with slude channels for conveying sludge radially inwards to a sludge receiving chamber, from which the sludge is discharged by means of a central sludge discharge means, the openings of the sludge channels into the sludge receiving chamber are controlled by a slide member being biassed to move in one axial direction by spring means.  To cause the slide member to move in the other axial direction, a pressure chamber, sealed against the sludge receiving chamber, is disposed between the slide member and the rotor, and a fluid channel ex-tends through the rotor to the pressure chamber, connecting the pressure chamber with a pressure source located outside the rotor.          A position regulator is disposed in a cavity of the rotor, and is arranged to operate directly of said slide member for regulation of its position.

Abstract: Method and Apparatus for Applying a Polymer Layer to a Metal Sheet Abstract Disclosed is a method and fixture for applying a thin layer of polymer material (26) to a piece of wavy sheet metal (24)(34).  The sheet (34) is drawn to the smooth surface (42) of a fixture using a vacuum, and polymer (49) is flowed across the surface (51) using a curved leveling board (50) which produces a generally uniform thickness polymer molding.  The edges (76) of the layer are molded with a bevel edge by shaped side rails (38) to pro-vide a relief around the edge of the layer.  Thus a raised up polymer portion (68) usually occuring at the edge rail (38) location will not interfere with the precise spacing which the layer is intended to produce between the sheet and a cylindrical workpiece holder (20).

Abstract: Abstract of the Disclosure The agricultural harvester 10 cooling system induces a heat exchanger 38 or cooling an internal combustion engine 32 and a heat exchanger air cleaner assembly 36.  The heat exchanger air cleaner assembly has a fixed screen 62 adjacent the heat exchanger 32 which forms one wall of a large box 45.  Channel members 64 and 66 and flat bars 68 hold the fixed screen 62 in a plane and form a plurality of pie-shaped compartments.  The air cutoff plate 78 on rotatable shaft 72 closes the pie-shaped compartments and substantially blocks the flow of air through the fixed screen 62. A suction wipe 84 adjacent the fixed screen 62 and inside the large box 45 rotates with the rotatable shaft 72 directly across the fixed screen from the cutoff plate 78.  The suction pipe 84 is connected to the intake of a centrifugal blower 118 by a vacuum pipe 96.  The centrifugal blower 118 sucks trash from the fixed screen 62 and through a long slot 88 in the suction pipe 84 as the suction pipe 84 is moved along the surface of the fixed screen 62 by the rotatable shaft 72.  The large box has a fixed air inlet screen 60 in the top wall 56.  Hinge 58 which connects the large box 45 to the support frame 40 allows the fixed screen 62 to be pivoted away from the heat exchanger 38 for service.  An oil cooler 108 is positioned between the fixed screen 62 and the heat exchanger 38 and is also connected to the support frame 40 by the hinge 58.

Abstract: Abstract Selectively Openable Seal Line and Containers Having Same A unique selectively openable seal line made between two sheets of flexible thermoplastic material is disclosed, the seal line being exceptionally resistant to unintentional opening forces but being easy to open upon the application of a specific force.  The seal line may be employed in various containers, including a two chamber container for the separate storage and selective mixing of two medical substances.  The container includes two sheets forming the exterior of the container and an inner, diaphragm sheet between the outer sheets.  The selectively openable seal line is disposed between one of the outer sheets and the diaphragm sheet.  Preferably a permanent line of securement is also included, between the other exterior sheet and the inner diaphragm sheet, extending substantially parallel to and coextensive with the openable seal line.  Such a container provides a relatively inexpensive and reliable means for separately storing two medical substances in a closed system under sterile conditions, while still providing for quick and easy selective mixing of the substances when desired.          Finally, the present invention is also directed to a sealing die for making the unique seal line and to a method for manufacturing the container.

Abstract: SEALING MEMBER FOR ROTATING SHAFT AND METHOD       OF SEALING THEREWITH             Abstract of the Disclosure An improved sealing sleeve for the rotating drive shaft of a gear 5 pump or other fluid conveying system has an internal axial bore for receiving the shaft, an intermediate cavity formed in the bore and oppositely-handed helical channels extending in the bore on opposite sides of the cavity. The inward heli-cal channels are of a hand relative to the shaft rotation for effectively pumping viscous fluid entering the annular spacing between the shaft and sleeve toward 10 the cavity while the oppositely-handed outward helical channels effectively resist and overcome such pumped fluid flow, creating a static containment of the viscous fluid to produce a viscous seal about the shaft. Cooling fluid is conveyed through an annular passageway about the outward helical channels to solidify any viscous fluid entering the adjacent region of the outward channels to produce an outward 15 essentially mechanical seal about the shaft.

Abstract: ABSTRACT:            A storage disc has a transparent substrate (21) on which a recording layer (22) has been deposited, which layer can be modified locally by means of a radiation beam and is covered with a cover disc, for example in the form of an identical second transparent substrate (23) which is spaced from the recording layer and secured to the first substrate by annular means (26, 27) so as to enclose a sealed space (24). Protective circumferential means (25) form part of the annular means (26) to protect the peripheries (29) and (214) of both substrates which are vulnerable to impact forces and thermal stresses. It is essential that spaces (212, 213) are formed between the substrate peripheries and the circumferential means in which no means are present which can transmit undesirably large forces in the case of deformation of the circumfer-ential means. Thus, all forces, or at least such a part of the forces that fracture of the substrates is prevented, are transmitted via the annular means to the flat sides of the substrates only. The circumferential means may be subjected locally to plastic deformation to absorb impact energy.

Abstract: Abstract of the Disclosure A system to provide warning whenever unreliable data is being  received  by  an  airborne  receiver  for a  microwave landing system.  The received data is tested against certain criteria to determine validity.  The received data is also tested to determine whether  it was  received via a direct path  or  via  a  multipath  reflection.   A  validity  counter records the percentage of valid data received.  A multipath counter  records  the  length  of  time  data  is  received via direct path relative to the length of time data is received via multipath.  Both counters control warning flags to cause a warning to be generated whenever the counter contents are below threshold values.  The validity counter is set to an upper  limit  when its  count  crosses  the  threshold  in  a positive direction and is set to a negative limit when its count  crosses  the  threshold  in  a  negative  direction.   A constant  number  is  added  to  the  count  of  the  multipath counter  whenever  its  count  crosses  the  threshold  in  a positive  direction  and  the  count  is  cleared  completely whenever  the  count  crosses  the  threshold  in  a  negative direction.
